Troodontid Tooth | Hell Creek Fm. | Montana

An authentic, naturally shed Troodontid dinosaur tooth (Pectinodon bakkeri) from the Late Cretaceous Hell Creek Formation.

Historically assigned to the catch-all taxon Troodon formosus, these teeth from Hell Creek are now recognised as Pectinodon bakkeri. Pectinodon was a small, highly specialised bird-like theropod (measuring an estimated 2 meters in length) that possessed one of the largest brain-to-body size ratios of any Cretaceous dinosaur, along with large, forward-facing eyes adapted for low-light hunting.

This specimen showcases the diagnostic hallmarks of the species: a strongly compressed, recurved crown lined with comb-like serrations (denticles) that hook upward toward the tip. A rare tooth from one of the final and most intelligent non-avian dinosaurs.

The formation where this tooth was found, the Hell Creek Formation, was laid down by ancient floodplains in the Late Cretaceous and preserves fossils of Triceratops and Tyrannosaurus, as well as many other well known dinosaurs. Its top, the K-Pg boundary, marks the asteroid impact that ended the dinosaurs.

The tooth comes stored in a display box featuring the specimen name, region it was found and age.

This is genuine fossil. All the specimens we offer come with a lifetime authenticity guarantee.
